today looks pretty okay...
in 1997, when i was working at the old Woodlands Checkpoint, a
whole lot of us were dumbfounded when after the morning shift, we
went to the lockers, came out and saw a cloud of smog move in from
across the causeway...
we were planning to go have something to eat across the border but
after that, without a word, we just went home 
this year's isn't anywhere near as bad as that year... but the max
was around 150 this year...
